问题描述 Spring Cloud Feign调用其它服务报错,错误提示如下:Failed to instantiate [java.util.List]: Specified class is an interface. 解决方案 通过查询一些资料,得到的结论,是定义接口传递的参数时,没有用@RequestBody修饰,查看定义接口有用@RequestBogy修饰,Feign的接口实现里没有用@RequestBody修饰,添加后问题就解决了,以后还是要仔细看待每个问题.
举个例子: a.js ; module.exports.a = a; b.js var result = require('./a'); var getA =() => { console.log(result.a); } 然后打包生成: browserify b.js > bb.js 然后在页面端调用时,报getA() is not defined的错误: <script src="bb.js"></script> <script> g

No operation was found with the name xxx 出错原因是因为发布服务的接口所在包路径和此接口实现类包路径不一致,比如你的服务接口可能放在了包com.x.interFace下,但是你的实现类却在com.x.interFace.impl包下,此时,发布的服务被客户端动态调用(JaxWsDynamicClientFactory)的时候,就会报错: org.apache.cxf.common.i18n.UncheckedException: No operation

struts 2.3.16 採用动态调用发现不工作报404 not found,网上查找原因: 1.由于:struts2中默认不同意使用DMI 所以:须要在配置文件里打开: <constant name="struts.enable.DynamicMethodInvocation" value="true"/> 改动发现报No result defined for action 2.错误信息来看,是说未定义result. 你有没有配置拦截器<in
